Product Description

Perforated metal tube is made of perforated metal mesh with a wide range of perforated patterns and open area percent&period; It can be made from a variety of materials including stainless steel plate&comma; hastelloy plate and mild steel plate through punching and welding&period; The perforated metal tube can be punched in round hole&comma; square hole&comma; rectangular hole&comma; hexagonal hole and special openings&period; And the welding type can be direct welding or screw welding&period; Because of its perforated structure&comma; this type of filter can offer superior resistance to bending and crimping&period; So it is the ideal choice to be used where need rigidity and durability&period;

Advantages of stainless steel perforated tubeStainless steel&comma; unlike carbon steel&comma; features rust resistance and corrosion resistant&period; It contains chromium&comma; when exposed to oxygen&comma; creates an invisible protective film&period; Stainless steel types are classified into three different groups based on their ability to be hardened&period; Austenitic stainless steel&comma; which can be hardened by cold working condition&comma; meets a wide range of design criteria&period;

Commonly Perforated Stainless Steel Types

304 &lpar;Austenitic&rpar;One of the most widely used general-purpose stainless steels&period; It possesses an excellent combination of strength&comma; corrosion resistance and fabricates well&period; To reduce carbide precipitation when welding&comma; use 304L for its lower-carbon content&period;

316 &lpar;Austenitic&rpar;Superior corrosion resistance compared to other 300 series alloys when used in used harsh corrosive environments &lpar;ex&period; sea water&comma; chemicals&comma; etc&period;&rpar;&period; To reduce carbide precipitation when welding&comma; use 316L for its lower-carbon content&period;

321 &lpar;Austenitic&rpar;Titanium stabilized stainless steel to prevent intergranular formation of chromium carbide&period; It exhibits strength characteristics superior to those of 304 stainless&comma; thus making it best suited for parts which cannot be subsequently annealed&period;

410 &lpar;Martensitic&rpar;The lowest alloy content of the three general-purpose types&period; It is a heat-treatable chromium type used for highly stressed parts needing the combination of strength and corrosion resistance&period;
